I met an interesting problem recently and am expecting your kind advice.
my input file (for_test) is like as follows. I wish add a to the
first line (before the word blue) and remove at the last line.
# ---begining of the file, this line is not included in the file---#
blue
sky

print OUTPUT @items\n;
When you place an array inside quotes, it's the same as saying
join($, @array)
where $ is the list separator variable, whose default value is (a
single space).
Thus, if @array is (this, that, those), then @array is this that
those.
